It's obvious that the simple strategy of buying any old investment property and watching it double in the space of 5 or so years, a strategy that worked in the early 2000's, isn't going to work in the next 5 (or more?) years.
I think CW is/was just trying to warn people who haven't cottoned on to this yet, and has done so in a very respectful and humble way.
Your posts are very much the opposite judging by your condescending tone (are you putting him in the "crackpot" camp?), and I'd suggest some humility wouldn't go astray.
I have no doubt that an astute property investor can make money in most markets, and if that's you, good luck! Keep doing what you're good at.
